MartinLogan Dynamo Outdoor Sub 100 In-Ground Subwoofer

Deep, Musical Bass. Beautifully Hidden Outdoors.

Bring exceptional low-frequency performance to your outdoor living space with the MartinLogan Dynamo Outdoor Sub 100, a premium 10-inch subterranean subwoofer engineered to deliver rich, powerful bass while blending discreetly into your landscape.

Designed for patios, gardens, pool areas, and backyard entertainment systems, the Dynamo Outdoor Sub 100 provides the depth and musical impact that conventional outdoor speakers often struggle to reproduce.

Powerful Bass Without Compromising Your Landscape

At the heart of the Dynamo Outdoor Sub 100 is a 10-inch mineral-filled polypropylene woofer with an oversized 2-inch voice coil, engineered to deliver clean, controlled, and authoritative bass.

With low-frequency extension reaching 33Hz (±3dB), this subwoofer brings impressive depth and richness to your favorite music, creating a more complete and engaging outdoor listening experience.

Its innovative subterranean design allows the main enclosure to be buried beneath the landscape, leaving only a discreet mushroom-style canopy visible above ground.

The result is exceptional bass performance without the visual intrusion of a conventional speaker enclosure.

Built for Demanding Outdoor Environments

The Dynamo Outdoor Sub 100 features a rugged, high-density polyethylene enclosure designed to withstand moisture, temperature extremes, and challenging outdoor conditions.

Its IP58-rated construction provides outstanding protection against dust and water, making it an excellent choice for permanent landscape audio installations.

A specially engineered flared port helps deliver powerful bass with minimal unwanted noise, while the canopy design protects the enclosure and allows the driver to operate efficiently.

The Foundation of Exceptional Outdoor Audio

Outdoor environments present unique challenges for bass reproduction. Without walls to reinforce low frequencies, even excellent outdoor speakers can struggle to deliver the fullness and impact of a premium indoor audio system.

The Dynamo Outdoor Sub 100 solves that challenge with a purpose-built underground enclosure and a powerful 10-inch driver.

Pair it with MartinLogan Outdoor Sat 40 or Outdoor Sat 60 landscape speakers to create a beautifully balanced outdoor audio system with exceptional clarity, impressive dynamics, and satisfying bass throughout your property.

The Dynamo Outdoor Sub 100 is also the subwoofer included in MartinLogan's Outdoor Living 4.1 System.
